Abstract:

Abstract:This paper describes the Tianjin Huaneng Yangliuqing thermoelectric Corporation Limited.three No.5 unit dispersed control system
(DCS) transformation of the latter,debugging process,The boiler side sequence control logic system (SCS) to optimize the process.(this paper)To early to SCS in different stages of the design,configuration and debugging of the main problems are analyzed,and in view of the defects of the original design logic proposed the solution.After optimization of SCS runs smoothly,the interlock protection action of unit is more accurate and reliable.
